Responsible research and innovation aspires to anticipate and assesses potential implications of innovations. Hence, emerging technologies are a crucial issue for this mode of foresight and governance. The case of nanotechnology demonstrated that discourses on those emerging technologies are increasingly shaped by techno-utopian narratives. We argue that these narratives are here to stay, because they are an expression of a contemporary medialization of science and technology. Since the RI community can neither ignore nor escape these techno-utopian narratives, it might engage in a hermeneutic reading of these visions as performative fiction. We use the case of desktop 3D printing to demonstrate in what way an analysis of techno-utopianism is able to reveal how responsibility for innovation gets redistributed.
